Hi, I''m using Xen 4 (version 4.0.1~rc3-1 from Debian sid), with a 2.6.32.16-*-gb97a312 pv-ops kernel (the stable-2.6.32 branch) ; on a Debian Squeeze amd64 system, with udev version 158. When I try to create a DomU, with a bridge setup, I obtain that : # time xm create /etc/xen/slhoka.cfg Using config file "/etc/xen/slhoka.cfg".
